Hi everyone! We built How Many Cameras to help answer a practical question before buying security cameras: how many do I need, and where should they go? Pick a home template, mark the areas you want to cover, set installation constraints, and adjust camera positions. You can then compare cameras, doorbells and smart locks using three-year costs, including subscription and local-recording options. The planner is free and does not need an account. It is designed for US and Canadian homes. Layouts are illustrative and product data comes from manufacturer specifications, so please check the live view and conditions at your property before installation. The site uses affiliate links to support the project. Which layout or installation constraint would make this more useful for your home?
